Ruflorinia
''Ruflorinia'' is a genus of fossilized foliage from the Early Cretaceous of Argentina assigned to the order Caytoniales. Taxonomy The genus was first established by Sergio Archangelsky based on material from the Anfiteatro de Ticó Formation, Santa Cruz, Argentina, with the type species being ''Ruflorinia sierra''. The genus name celebrated the Swedish paleobotanist Rudolf Florin. Other two species (''R. pilifera'' and ''R. papillosa'') were later described from the Anfiteatro de Ticó and another (''R.orlandoi'') was later described from the Springhill Formation in Argentina. Paleoecology In the Anfiteatro de Ticó Formation, leaves of this genus are found in association with the ovulate organ ''Ktalenia'', and the conifer ''Brachyphyllum ''Brachyphyllum'' (meaning "short leaf") is a form genus of fossil coniferous plant foliage. Plants of the genus have been variously assigned to several different conifer groups including Araucariaceae and Cheirolepidiaceae. The ...

Sergio Archangelsky
Sergio Archangelsky (27 March 1931 – 10 July 2022) was an Argentine paleobotanist and palynologist. He was a pioneer of modern paleobotany in Argentina, as well as of cuticular morphology and ultrastructure. He was also a corresponding member of the Argentine Academy of Science. Biography Sergio Archangelsky was born on 27 March 1931. He obtained his master's degree in geology (1954) and his doctorate (1957) at the University of Buenos Aires. While preparing for his doctorate, he started working in Tucumán (1955–61), at the Lillo Foundation, where he later will become Professor of Paleontology and geology. Thanks to a fellowship from the British Council, he was able to visit Britain, where he spent time working at the University of Glasgow, the University of Reading, and the Natural History Museum in London, where he interacted and collaborated with Thomas Harris. In 1961 he became a member of the CONICET and was Professor of Paleobotany at the Museum of Natural Sciences ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesodescolea
''Mesodescolea'' is a genus of fossil foliage with uncertain affinities from the Early Cretaceous of Argentina and Antarctica. It includes only one species, ''Mesodescolea plicata''. Taxonomy The genus was first erected by Sergio Archangelsky based on material from the Aptian of the Anfiteatro de Ticó formation. The name of the genus is dedicated to the naturalist Horacio Descole. Although it was originally compared to cycadalean genera such as '' Ctenis'' and ''Stangeria'', its affinities were originally considered uncertain. Later reinvestigations and emendations cemented the view that ''Mesodescolea'' was a member of the Cycadales family Stangeriaceae. Other authors have proposed that the genus represents a member of the angiosperms with affinities with the ANA grade or Chloranthaceae. Description The genus includes leaves with highly lobed-dissected margins. The venation is hierarchical, with the tertiary veins forming an irregular reticulum. Chloranthoid teet ...

Plantae
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caytoniales
The Caytoniales (Figs. 1-2) are an extinct order of seed plants known from fossils collected throughout the Mesozoic Era, around . They are regarded as seed ferns because they are seed-bearing plants with fern-like leaves. Although at one time considered angiosperms because of their berry-like cupules, that hypothesis was later disproven. Nevertheless, some authorities consider them likely ancestors or close relatives of angiosperms. The origin of angiosperms remains unclear, and they cannot be linked with any known seed plants groups with certainty. History The first fossils identified in this order were discovered in the Middle Jurassic Gristhorpe bed of the Cloughton Formation in Cayton Bay, Yorkshire, with the name of the bay giving the name to the group. They have since been found in Mesozoic rocks all over world. It is likely that Caytoniales flourished in wetland areas, because they are often found with other moisture-loving plants such as horsetails in waterlogged pal ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Argentina
Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. It shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state subdivided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, and a part of Antarctica. The earliest recorded human prese ...

Santa Cruz Province, Argentina
Santa Cruz Province ( es, Provincia de Santa Cruz, , 'Holy Cross') is a province of Argentina, located in the southern part of the country, in Patagonia. It borders Chubut Province to the north, and Chile to the west and south, with an Atlantic coast on its east. Santa Cruz is the second-largest province of the country (after Buenos Aires Province), and the least densely populated in mainland Argentina. The indigenous people of the province are the Tehuelches, who despite European exploration from the 16th century onwards, retained independence until the late 19th century. Soon after the Conquest of the Desert in the 1870s, the area was organised as the Territory of Santa Cruz, named after its original capital in Puerto Santa Cruz. The capital moved to Rio Gallegos in 1888 and has remained there ever since. Immigrants from various European countries came to the territory in the late 19th and early 20th century during a gold rush. Santa Cruz became a province of Argentina in 1957. ...
